Tensile ductility of lamellar microstructure is higher than that of equiaxed one at 20 K. Its deformation process consists of twinning and slipping.
低温下粗大的片状组织比等轴组织具有更高的拉伸延性，且合金的变形是由孪生变形和滑移变形共同作用的结果。
Also, both the number and the width of shear bands were increased, which cut twinning bands and refine more area of microstructure.
同时剪切带的数量和宽度都增加，产生相互交错并切割孪晶板条，使基体的细化面积增大。
The microstructure of Twinning Induced Plasticity (TWIP) steel during tensile deformation was investigated with SEM and TEM.
采用扫描电镜、透射电镜对TWIP钢的拉伸变形过程中的孪晶进行了观察。
